The Optogate PB-09 is our new automatic microphone gate unit, implemented in a table stand. The PB-09 contains a mic on button what can be used as "push to talk" or "mic latch" switch. These different functions are user programmable with 3 dip switches. The PB-09 contains also a galvanically separated trigger input for the mic control. The switching noise is not measureable. A red status LED indicates if the microphone is switched on. The PB-09 works with 48V phantom power and can be used in connection with dynamic mics and condenser mics. The phantom power passes the microphone. The 1,2 kg heavy body of the PB-09 is iron made and equipped with 3 anti noise rubber feet on the bottom in order for a safety silent fixed position. The PB-09 is the best all in one solution for conference applications.
